Christophe Thomazo

Christophe Thomazo is a Professor at the University of Burgundy (Université Bourgogne Franche-Comté), specializing in geochemistry and biogeosciences. He leads research on microbialite formation, early Earth geochemistry, and isotope geochemistry. His work integrates field studies, laboratory analyses, and theoretical modeling to explore environmental transitions, redox dynamics, and biogeochemical cycles in ancient and modern systems.

Key research focuses include:

• Microbialite mineralization mechanisms in alkaline lakes
• Isotope geochemistry of carbonates and sulfides
• Environmental proxies for ancient oceans and atmospheres
• Instrument development for in situ isotopic analysis
• Interdisciplinary studies linking geology, biology, and chemistry

Publications emphasize Paleoproterozoic to Archean environmental changes, with recent work on ferruginous lake systems, Neoarchean weathering patterns, and oxygenation history. He collaborates globally on projects like the 3.5 Ga Middle Marker Horizon and the Great Oxidation Event.

Teaching responsibilities include undergraduate and graduate courses in geochemistry, field methods, and biogeosciences.
